Summary:
The parking brake is a crucial but often overlooked safety feature in vehicles. Initially integrated into the hydraulic brake system, early designs could seize if unused, leading to costly repairs. While modern parking brakes have improved, their regular use remains essential. They prevent vehicles from rolling when parked and serve as a backup if the hydraulic brakes fail. Regulations require them to hold a vehicle on a 20-degree incline and function independently from service brakes.
Experts advise using the parking brake every time you park, even on flat ground, to reduce strain on the transmission and prevent excessive wear on the parking pawl, which can be made of plastic. Engaging it regularly also prevents rusting or seizing. Driving with the parking brake engaged can cause brake overheating, excessive wear on tires and brake components, poor fuel efficiency, and even brake failure.
Despite the rise of electric vehicles (EVs), manufacturers continue to prioritize parking brakes, with many models featuring automatic electronic versions. This indicates their continued importance for safety and stability. However, you need to be cautious in freezing conditions—after driving through snow or ice, setting the parking brake can cause it to freeze, locking the wheels and making the car immobile.
The parking brake is not just a relic of older vehicle designs; it plays a vital role in maintaining vehicle safety and reliability. By using it correctly and regularly, drivers can extend the life of their transmission, reduce wear on crucial components, and ensure their vehicle remains secure when parked. While exceptions exist, such as during freezing weather, the parking brake remains an essential feature that should not be ignored.
